Revision as of 01:06, 5 September 2008

Purpose

This is intended to be a page to keep track of the correct turns ratio of spinner/dial/paddle/trackball-controlled arcade games. Below is comma-separated text, hopefully this is a useful format.

Q: How do I use this information?

A: To tweak the analog sensitivity in MAME to better emulate real hardware.


An example from the first link below: Tempest, 72 count

if the control you use has 1200 counts per turn, the sensitivity calculation is: Sensitivity = 100 * 72 / 1200 = 6%

Data

Effective_Tooth_Count = teeth that pass through the optical sensor per revolution of the knob (multiply by any gear ratios to obtain)

Counts_Per_Revolution = could be 1x, 2x, or 4x of the Effective_Tooth_Count (depends on original hardware interpretation of optical sensor information)

Other_Notes = quantitative information relating to game play (like degrees of turn from one side of the screen to another - useful for potentiometer games like Warlords)

Game Effective_Tooth_Count Counts_Per_Revolution Other_Notes
720 degrees 72 144
Arkanoid 486 486 Geared: The knob attaches to shaft #1, which has a 72 tooth gear on it. That gear turns a 16 tooth gear on shaft #2. Shaft #2 also has a 72 tooth gear on it, which then turns a 16 tooth gear on shaft #3. Shaft #3 also has the encoder wheel on it, which has 24 teeth. 120-130 deg = one traversal across the screen
